The Oakland Athletics stunned the Detroit Tigers with a ninth inning rally that snatched victory from the jaws of defeat and forced an ALDS Game Five.

Trailing 1-3 in the ninth, the A's refused to leave the playoff party. Seth Smith's two-run double tied the game at 3-3 and then Coco Crisp hit a walkoff single with two outs in the ninth to give the A's a 4-3 win in Game 4.

Crisp was covered in pie by celebrating teammates. Detroit Tigers' Jose Valverde blew the save. The Tigers will now face a win-or-go-home Game Five in Oakland, although pitching ace Justin Verlander is likely to start.

The New York Yankees also came back in the bottom of the ninth, with Raul Ibanez scoring the tying home run with his first at-bat, coming in to pinch hit for a struggling Alex Rodriguez. Ibanez struck again in the twelfth to claim a 3-2 victory over the Baltimore Orioles. The Yankees lead the series 2-1 with Game Four on Thursday.

The San Francisco Giants also tied up their series 2-2 against the Cincinnati Reds, who had taken a 2-0 lead in California but have lost both games at home. The Giants won 8-3. Game Five will be in Cincinnati on Thursday.

The St Louis Cardinals silenced 45,000 Nationals fans enjoying the first baseball playoff in Washington for 79 years. The Cardinals won 8-0 to claim a 2-1 NLDS lead.
